Microphone?

Hi guys,

I am getting the Logitech C920 HD Pro Webcam with my computer.

(http://www.pccasegear.com/index.php?main_page=product_info&cPath=3&products_id=20151)

It says that there are dual stereo microphones in it. Will I need any other microphone?

I will only be using Skype and gaming etc. Nothing fancy.

Will this be fine and will the mic work when the video is turned off?

Thanks,
